The bubbler is located
laterally in the machine and
serves two purposes: cleaning the Hydrogen gas and act as
a safety barrier against a flame. If a flame reaches the bubbler and ignites the reduced hydrogen accumulated
at the top of the bubbler but the water column will prevent the flame to reach the main tank where there is
much more hydrogen accumulated.
The bubbler comes already filled with a light acid solution from
factory. The level of this solution should be kept between the 2
marks in the metallic protection. If the level drops below the inferior
mark then you should refill the bubbler.
For refilling the bubbler, please follow these simple steps:
1. The solution to use is a light acid, like vinegar (Ph 3);
2. Open the threaded cap positioned on the top of the bubbler;
3. With a small funnel, pure gently the solution and check at the
same time the level rising inside the lateral hose of the bubbler;
4. Stop pouring when the level reaches the maximum level mark;
5. Close the threaded cap. If necessary add a little bit of Teflon tape
to tight it better.
